I don't know if anyone else has had this problem but it seems that when I receive new or replacement credit cards and call the 1 -800 numbers that the sticker has they are never able to "verify" that I am calling from my home phone. It doesn't seem to matter which company. This is becomming a frustrating expeirence. I would appreciate some knowledge on this issue. I did not have this problem before I started using Vonage. (Had a standard phone line.) Thanks,

The credit card company is using the number on file, which would be whatever number you have given them.

The problem is (in my case), Vonage "caller-id" number is not always your telephone number. If you wish to find out what number is being given, you could call a number which will verify the ID being sent. I have used the, pardon the company, MCI sign-up number. The number will read back your number that their computer is receiveing. 800-join-mci.
